"Some of these updates are going to be more wholesale than others are," Bryan Dyer, city planner, said Wednesday morning at the mid-month study session of the Lawrence-Douglas County Planning Commission.

Updates to the commercial land use and transportation elements of the plan are already in progress. Spring should bring reviews of chapters concerning economic development and industrial land use, followed by growth management in summer 2002, planners indicated.

Those efforts will be followed by updates to the parks and community facilities sections of Horizon 2020 in fall 2002, and conclude with an update to the historic preservation chapter.

Horizon 2020 was originally adopted in 1996 by the Lawrence-Douglas County Planning Commission, and by the Lawrence and Douglas County commission in the succeeding years.

Some amendments have already been made, but nothing like the concerted effort now planned.

"The conditions for the city and county have changed since the comprehensive plan was adopted the population projections are bigger than we thought, for example," Dyer said. "The chapters should reflect those changes."

He said the public will have opportunities to affect the revisions.

"Public input will occur at all the planning commission, city commission and county commission meetings," Dyer said. "There will definitely be opportunity for public input."
